The invention relates to a machining device for machining a narrow side of an, in particular plate-shaped workpiece. Such a machining device can particularly be used in the field of the furniture and component industry. Machining device has: a machining unit for machining a narrow side of a workpiece, a conveyor unit for moving the workpiece in a transport direction relative to the machining unit, a detection unit for detecting an optical and/or three-dimensional structure of the workpiece moved by means of the conveyor unit, and a holding unit for holding the workpiece at the conveyor unit at least between the position of the detection unit and the machining unit.

In an embodiment, a machine tool includes two fixed modules and two movable modules each of which having a main spindle, a headstock, and a tool post being integrally formed, and a bed on which these are installed. The movable modules are provided on the bed to be movable in the Y-axis direction, the fixed modules are fixed on the bed on the opposite sides of the these movable modules, and a recess is provided next to the fixed module, the recess being formed by cutting out the bed. The movable modules are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle of the fixed module or the fixed module. The movable module is movable to the opposite position of the recess.

A machining system including a base; multiple work modules arranged in an arrangement direction on the base, at least one of the multiple work modules being a processing module, which processes a work with a tool, provided with a main shaft head including a main shaft on which a tool is attached and a main shaft rotating device that rotates the main shaft; a head raising and lowering device that moves the main shaft head in a vertical direction; a head moving device that moves the main shaft head in a horizontal plane by moving it in two perpendicular directions; and a work table that holds a work; the processing module being configured so as to be pulled from the base along a path extending in an intersecting direction, which is a direction perpendicular to the arrangement direction.

Material removal processes of a structure are disclosed. These processes can define several features. For example, metal structure can include an interior recess surrounded by a sidewall. The structure can further include a base portion integrally formed with the sidewall. The sidewall can include an opening extending through the sidewall and into the interior recess. The sidewall can undergo a material removal process to include multiple curved regions. The sidewall, the first curved region, and the second curved region can be polished to include a reflectivity different than a reflectivity of an exterior region of the base portion. A single multi-axes lathe having multiple spindles performs several material removal processes under a continuous machine cutting process. The spindles may include clamping features that allow a first spindle to perform a first operation then pass the metal structure to a second spindle. Additional processes include lapping, polishing, and linear brushing.

The present disclosure relates to an apparatus for chamfering at least one edge of the gearing at the front side of a workpiece having internal gearing comprising at least one rotatably supported workpiece holder for holding the workpiece and comprising at least one rotatably supported tool holder for holding at least one chamfer hob, possibly a chamfer cut hob, wherein the tool holder is arranged and/or arrangeable next to a workpiece held in the workpiece holder and a chamfer hob held in the tool holder is arrangeable by means of a tool arbor in the region of the center opening of the workpiece formed by the internal gearing to be brought into engagement with an edge of the internal gearing on the upper side and/or on the lower side of the workpiece.

A machine tool includes a base, a table, a main spindle, and a trunnion unit. The table is installed on the base. A tool is mounted to the main spindle. The main spindle is caused to approach a workpiece on the table along an up-down direction. The trunnion unit is configured to rotatably hold the table on which the workpiece is placed using a rotation axis along a front-rear direction as a center. The trunnion unit is disposed movable in a right-left direction.

In an embodiment, a machine tool includes two fixed modules and two movable modules each of which having a main spindle, a headstock, and a tool post being integrally formed, and a bed on which these are installed. The movable modules are provided on the bed to be movable in the Y-axis direction, the fixed modules are fixed on the bed on the opposite sides of the these movable modules, and a recess is provided next to the fixed module, the recess being formed by cutting out the bed. The movable modules are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle of the fixed module or the fixed module. The movable module is movable to the opposite position of the recess.
